CONTAINER AND SEALING MEANS THEREFOR.

Application filed March 3, 1927. Serial No. 172,376.

my invention relates to containers which are provided with bungs in the form of threaded the threa ed interiors of bushings that are tainers, the invention findin particular use 'in connection with barrels 1n whichoil or other liquid ispackaged for shipment.

The invention has for its object the provision of means for obstructing undetectable access to and removal'o'fithe plugs. To this end I employ a sealing device assembled with a container wall and positioned to prevent undetectable access to or undetectable removal of the plug, which usually has a tool engaging formation upon its outer end, access to which is preferably obstructed by the sealing device.

In accordance with'one feature of the invention, the sealing device is inclusive of a hood which preferably completely covers the otherwise exposed outer end portionof the plug so that not only is the undetect-v able removal of the plug guarded against but access to the tool engaging formation of the lug-is guarded against and access of 'other islodging tools such as chisels and punches is also guarded against. In the preferred embodiment of the invention, the

sealing device is inclusive of a portion that is confined and preferably clamped in the space between the container wall and a flange that is provided upon theouter end of the bushing. The portion of the sealing device thus preferably held in place is weaved through the hood and overlies or laps its top and overlies or laps the outer .end of the plu ,whereb the hood is held in position an is guar ed from undetectable removal. The plug is desirably also provided with a flange that clamps a gasket upon the bushing flange.

The invention will be more fully explained in connection with the accompany ing drawin in which Fig. 1 is a view illustrating t e preferred embodiment of the invention, the bushing-and a portion of the container wall being shownin section while the plug and the sealing device that-protects its outer end are shown in elevation; Fig. 2 is a view similar to Fig. 1 but showing the sealing device and plug also in section; and Fig. 3 is a sectional view.-on}line 33 of Fig.2. The container, such as a barrel, has one lugs which are received within wall 1 thereof formed with 9. depending rim 2 which surrounds a circular hole formed through this wall.- An interior-1y threaded bushing 3 is snugly received within this hole and is closely surrounded by said rim, this bushing being shown with an outwardly curled inner edge portion 4 which grips the inneredge of said rim 2 and a circumscribing flange 5 which is tightly seated upon the wall 1, this flange desirably lapping this wall on the exterior of the-container. The flange 5 is of hexagonal or other polygonal contour, the'wall -1 being formed with a' pocl et receiving (said flange, this pocket having a flange encompassing wall 6 which is polygonal in contour and snugly engages the perimeter of the flange to prevent the bushing fromturning. The closure plug 7 is screwed within .the bushing 3 and is formed with a circumscribing flange 8 which laps the flange 5 and wall 1, an annular sealing gasket 9 being desirably interposed.

between the flanges to render the joint bethe body of the plug, thls recess being of square or other contour to receive a Wrench having a plug formation snugly receivable within and corresponding in .shape to said recess. 7

The sealing device ofmy invention is preferably inclusive of a plug protectin element in the-form of a hood 12 whic encloses the plug portions 8. and 10 and has the rim of its skirt laterally extended as indicated at 12' and resting upon the top of the pocket that receives the. bushing flange 5. A guard isemplo ed to hold the hood in place, this guard inc uding t'wo strip mem ers 13 WhlCh have angular, base portions 100 13' that receive corners of flange 5 and are' received in the angular corners of the aforesaid pocket formed in the wall 1 to receive the bushing flange 5, the base portions 13' being clamped or confined between the flange 105 5 and wall 1 and snugly received between the perimeter of said flange and the surroundingwall of said ocket. Said ard portions 13 are thus eld from shi ing.

They are. surrounded by the rim of the 110 .All of the hood skirt andpw through the skirt to the exterior of the hood. Said guard is completed b 'a sealing wire 14] that -laps the 'plug an overlies the top of the hood and is so close thereto as Ito hold the hood in place. The wirepasses through holes in the upper ends of the'strips13 and is assembled with said strips. in any suitable manner as by solder, marked for identifi-' cation.- 1 v lugupo'n the exterior of the container is t us thoroughly guarded from undetectable access and undetectable removal'by'the construction-described. The bushing 3 and its. flange 5 surrounds the rtion of the plug that is in their zone. he

seal structure encloses and protects all ofthe 'plug in the outer zone adjacent theflange5. The material ofwhich' the hood is made is desirably very thin sheet metal such as tin which will readily tear or become ruptured if any attempt is made to loosen the -to t e plug ange 8 or the plug en Having thus described my of an interiorly threaded bushing received in said hole and assembled with said wall, said bushing having a circumscribing flange of polygonal contour. and which laps the wall where the wall surrounds said hole, the wall being formed with angular ortions receiving angular portions of said ange to I prevent the bushin from turnin ;"a closure lar wall tions receiving said. angular portions of the plug screwed within the boreo the bushing; and a guard lapping the plug and having. a portion confined betweensaid contamer wall and bushing flange in said anguportions and having angular por- 2.

The coinbination with a containe formed with a hole through. a wall thereof; of an'interiorly threaded bushing received in said holeand assembled'with sa1d wall, said tion and surrounded by the hood at another bushing having a circumscribing flange of polygonal contour and which laps the wall where the wall surrounds said hole, the wall I -being formed with angular portions receiving angular portions of said flange to prevent the bushin from turning; a'closure plug screwed within the bore of the bushing;

a hood lapping the outer end of said plug to prevent undetectable access thereto; and

a guard confined between said container wall and bushing flange in said angular wall portions and having angular-portions receivin said angular portions of the flange, sai guard'being surrounded, adjacent said container wall,. by said hood and passin through the hood to the .exterior thereof an across the same.

4. The combination with a container formed with a hole through a wall thereof; of an 'interiorlythreaded bushing received insaid hole and assembled with said wall, said bushing having a-circumscribing flange which laps the wall where the wall surrounds said hole; a closure plug screwed withinthe bore of the bushing; a hood lapping the outer end of thqplug; and a guard assembled with said contalner wall and crossing the exterior of said hood at'one'porportion.
